Battery Information

Battery Charging

1. Connect the AC adapter to the charger pod and plug it into a power source.
2. Turn the radio off.
3. Insert the battery pack into the charger pod, either with or without the radio attached. The charger LED status light will turn red, indicating charging has begun.

• Ensure the radio is turned off before placing it in the charger, and never switch a radio on while it is in the charger.
• Only use Entel branded battery packs and chargers.
• Do not short the battery terminals or dispose of the battery in a fire.
• Do not charge the radio and/or battery pack if they are wet.

Danger

DO NOT DISASSEMBLE OR MODIFY THE BATTERY IN ANY WAY!

Your Entel battery pack incorporates a safety circuit to prevent danger. If this safety circuit is damaged or bypassed, or if the battery cells are damaged directly, they may generate extreme heat, smoke, rupture, and emit flames.
